The filter is located Under the unit in most air handlers, in a manufactures filter track, this is pretty universal from one air handler branding to the next. On most furnace installations you most likely will cut either 1 or both of the sides out of the furnaces blower compartment. This means you must remove the furnaces main door, then remove the two hex head screws in the blower door's front or top usually 5/16th hex head at top edge.

Open the furnace and check to see if the filter is located within. It should be neatly pinned in place with a thin metal wire, running from rear to front that clips inside and against the side of the furnace near the front.

Then there is the last kind of set up where we embed a filter track external to the equipment and with in the run of return ducting you may also use return filter grills in walls and ceiling where the main return louvers originate.

How do you install an air conditioner filter?

It depends if it is a central unit or a window unit. A central unit will have a return air duct with a hinged grate. open the grate and pull out the old filter. Check the size and go to the store and buy that size filter. Put the filter in the way you took it out. A window air conditioner either has a foam, fiber, or screen type filter. If it has a screen type, just pull on the tab that should say filter on it and slide it out. You can was this type in the sink, let it dry and then put it back in. The foam and fiber type you have to remove the front of the unit, usually held on by metal clips behind the facing. Pull the front off and pull the filter out. These have to be replaced

Do air conditioners work better when they have a filter in them?

Air conditioners, whether a window unit or a central unit, MUST have a filter. Otherwise, dust, lint, dirt, pet hair, etc. will clog up the cooling coils. The cooling coils are damp, and the dust and dirt, etc. will stick to them, which will result in the fan not being able to blow air through the unit. This will very quickly result in a unit that is damaged beyond repair.
